BEWARE - Penney's Power Bank melted !

A quote

1. Don't charge a power bank overnight. This can increase the risk of overcharging. So, as a safety precaution, you should avoid leaving your power banks to charge for an extended period of time, especially on bed or other soft surfaces that may build up heat.

Never leave anything charging on something combustible like a couch or a bed. It's also a bad idea to leave things charging out of sight and overnight. Especially these cheaper devices. But anything electrical and or with a battery can go faulty.

How is overcharging still a thing in this day and age? Reeks of them choosing to sell a product that cut too many corners.

And usb chargers with multi ports should not be sold if they are not safe

I had a similar one go on fire. The one with the oled display readout of %

I always place them in the crevice of a concrete block when charging so if it catches fire it won't spread.

Laptops and audio gear by reputable comapnies like Sony, Lenovo, Bose etc are 100% safe because they have a proper charging circuit built in. So when it reaches 99%, the charging circuit is automatically disconnected.

I've never seen those things in instruction manuals

No you are wrong. Putting this as a warning should not be a get out clause for the product. This is a dangerous design flaw. It should stop charging when it reaches 100%. If it keeps taking current after 100% or max capacity, the charging circuit is flawed or faulty. The item should be banned from this country if people experience this.

If Samsung, Sony and Bose allow this, and there is never a problem, then there is no excuse for Chinese companies who are flooding the market with dangerous tat. If they can't get their design right, their product should be stopped at the ports.

I would like to point out that there are many great Chinese companies who do this right.

Every radio you have bought in the last 10 years is Chinese in origin. 99% of them have no issues.

You might have no problem charging 24x7 but it wears out batteries much fast and increases the risk of problems. Unless it something designed to do that. Most of these devices aren't..

I feel like in going crazy In this thread.. why would the battery of a powerbank be any more dangerous than the one in your phone which many of us charge overnight under a pillow or on the bed etc?

You've no idea if the power bank or the charger are to spec or regulations. Either could be faulty or both.

I agree it should be checked not dismissed as user error. Likely be recalled.

Even if what you did was also wrong.

You've some hope a well known brand with an EU mark might be to standard. But too many of these usb chargers and batteries are from unknown not up any standard.

That people have bad habits and do stupid things does not make those things ok.

Theres was probably something in the documentation what input charge it took and not leave it unattended on flammable surfaces.
